Troubleshooting - Pentair PENTEK INTELLIDRIVE PID2000-1123 Installation Manual

Troubleshooting

Fault Display Possible Causes
Over Shorted output.
Current Motor current exceeded the S. F. Amp
Motor oversized or pump undersized.
Pump Jammed or locked rotor.
Over Power is cycling on and off.
Voltage
Faulty check valve on pump.
Under Low input voltage.
Voltage
No power for a short period of time.
Excessive load current.
Loss of a motor phase.
Loss of an input line.
Rotor Jam Exceeding S.F. Amps
Locked rotor.
Dry Run Well draws down too far, pump runs dry.
Under sized pump or motor.
Leak in the pipe system.
Intermittent transducer connection.
Cannot reach pressure setpoint.
Possible Leak
Ground Ground fault sensed in motor
Fault cables or in motor.
Motor cable too long
Open Intermittent connection.
Transducer
Open Connection
Failed transducer.
Actions
Check for any shorts in the motor cables.
Make sure that motor Service Factor Amps
are correct.
Make sure that pump and motor are sized
correctly.
Pull pump; check for debris in pump
Check for a generator or for switching on
the input line.
Check for back flow in the system.
Make sure that input voltage is above
190VAC
Check for brown out conditions
Make sure motor is sized correctly for the
application
Make sure correct voltage is present on all
motor leads.
Make sure correct voltage is present on all
input lines.
Make sure Service Factor Amps entered
are correct.
Make sure pump and motor are correct.
Pull pump; check for debris in pump.
Check water depth.
Make sure pump and motor are sized
correctly.
Check system for leaks.
Check transducer cable for loose
connections or damaged insulation.
May need to reduce pressure setpoint.
Check for a broken pipe or a large leak.
Make sure motor cable does not exceed
max length in specifications.
Check for damage or breaks in motor
cables.
Check motor.
Length of cable limited to 1,000' unless a
filter is used to reduce capacitance
between motor wires.
Check transducer cable for loose
connections or broken or damaged wires.
Check transducer wires for correct
connections and verify secure cable
connection to transducer.
Check voltage at the transducer terminals
(12-24Vdc). If voltage is present, then
transducer is faulty. Replace the transducer.
